Disgraced cyclist Lance Armstrong didn't tell Oprah Winfrey the full truth about his doping and lied several times on significant issues, says the official who has been investigating Armstrong for years. One of the lies was telling Winfrey he did not dope for his 2009-2010 return to the Tour -- a claim blood tests solidly refute says U.S. Anti-Doping Agency's CEO Travis Tygart. In a letter to Armstrong, Tygart says he offered him a deadline of February 6 to cooperate fully and truthfully in exchange for a possible lessening of his lifetime ban from sports. Tygart, whose damning report last fall led to the imposition of the ban and the stripping of Armstrong's seven Tour de France wins, speaks to Scott Pelley in a 60 Minutes interview to be broadcast Sunday, Jan. 27 at 7 p.m. ET/PT.
